Story
You can fill out an adoption application online on our official website.Meet River & Flora These two beautiful girls have already survived so much together. River and Flora were found trapped in the LA River channel for over 48 hours, struggling just to stay on their feet. By the time they were finally rescued, they were exhausted and could barely walk. Long Beach Animal Shelter stepped up for these sweet girls, and AZ Mastiff Rescue went to bring them to safety. Their cherry eye surgeries are now done, and River and Flora are ready for their forever home. These girls are truly bonded — they eat together, sleep together, play together, and love each other so much. They are like two peas in a pod. Flora is about 5–6 years old, and River is about 1–2 years old. They are house trained, have nice house manners, are dog friendly, and are quiet, calm, mellow couch potatoes. They are easy girls who just want a soft place to land and a family to love them. We would love to find a home open to keeping both girls together. AZ Mastiff Rescue will do a 2-for-1 adoption for the right family willing to give these bonded girls the home they deserve. After everything they survived together, it would be so sad for them to be separated. If you are looking for two easy, loving, gentle girls, River and Flora may be the perfect pair. You won’t be sorry. ❤️  Visit this organization's web site to see any additional information available about this pet.October 2, 2026, 5:41 am

She could be perfectly happy as an only dog, soaking up all the attention, or she would also do great in a home with one or two other dogs.   Lena is: Dog friendly House trained ️Crate trained Loves playing in water ❤️ Social, curious, and affectionate   She definitely has that classic Great Dane curiosity — “What are you doing?

Story
You can fill out an adoption application online on our official website.URGENT FOSTER NEEDED: Meet Delilah This is Delilah. She's just 4 months old, a sweet mastiff mix with her whole life ahead of her — and she was dumped at a shelter in California like she was nothing.She's a baby. She should be curled up on someone's couch learning what love feels like, not sitting in a kennel wondering what happened to her world.Here's the truth: a rescue is no place for a puppy. Puppies need so much more than a kennel can give them — socialization, potty training, gentle guidance, and most importantly, the chance to learn that people are safe and good. That only happens in a real home, with real routines, real love, and real patience. That's why Delilah needs a foster — not just a place to stay, but a soft place to land while we find her forever family.What fostering Delilah looks like: A safe home environment (we provide food, supplies & medical care) Help with basic training & socialization Patience while she learns the world isn't scary anymore Sharing her journey so we can find her the perfect forever homeYou don't have to have it all figured out — we're here to support you every step of the way. All we need is someone willing to open their heart and their home to a baby girl who deserves so much better than a kennel.Could you be Delilah's foster? Even a short-term commitment can change her whole life.

Story
You can fill out an adoption application online on our official website.❤️ MEET SAMMY & ROSIE — BONDED BEST FRIENDS LOOKING FOR A NEW HOME ❤️ Sammy and Rosie are both 4½-year-old English Mastiffs who have spent their lives together. Due to life changes in their home, these two sweethearts now need a new family. They are truly best friends and have been bonded for life. We would absolutely love to see them stay together, but we also know that finding a home for two giant-breed dogs can be difficult, so separation may have to be considered for the right homes. SAMMY Sammy loves going for walks, chewing on his dog toys, taking baths, and soaking up as much attention as you’re willing to give him! He’s the more affectionate, attention-loving one of the pair. His one major complaint in life? Lettuce. Absolutely not. ROSIE Rosie is the quieter, more independent girl. She loves curling up in her bed, going for walks, and even enjoys hanging out in the rain. Baths, however, are another story! She is very mild-mannered, sweet, and content without needing constant attention. And just like Sammy… lettuce is also firmly on her “no thank you” list. ❤️ Both are: House trained Well mannered Great with people Good with kids Good with other dogs Sweet, loving family dogs No known health issues Sammy and Rosie have already had their world turned upside down once. We would love nothing more than to find them a wonderful home where they can spend their next chapter feeling safe, loved, and wanted.
